แบบนี้ไม่มี Range Check Error แต่อาจจะผิดพลาดได้กรณีค่าตัวลบอาจมากกว่าตัวตั้งต้องลองทดสอบทีละรายการต่อไปครับ แต่เบื้องต้นได้มาแบบนี้ครับ แปลกจริงครับบางตาราง JOIN ด้วย VN ไม่มีค่าต้อง JOIN ด้วย date ที่เป็นเงื่อนไขแทนครับ ตอนนี้เหลือตรงแลบที่อาจจะต้องแก้ไขการ JOIN และเพิ่ม LEFT JOIN มาอีกจะลองดู แล้วจะรบกวนให้ช่วยทำสอบครับว่าถูกต้องหรือเปล่าครับ ขอบคุณครับ
